Hi leacom,

Click to expand...

The READA and WRITA instructions are extended in the '5402 DSP to use 20 bits so you can use them to read the extended program memory addressed by accumulator A and store in data memory AND to write data to the extended program memory addressed by accumulator A respectively. All other instructions (to access data) do not modify the XPC.

Hope it helps.

Regards,
George
